Thanks!
With the players at your disposal, it seems 4-1-3-AMR-1 is the best option if you want to go for safety first policy.
Gustafson off, with Tenoff on as DC. The rest of DL, DC, DR and DMC is quite default.
Best player Bonokoane should move back to MC to act as middle of 3-man midfield (can up-arrow him), MR selects himself and the other MC on the region close to ML. El Khetabb as AMR and Ayew as ST.
Attack only via right flank. Normal/Defensive. Mixed/Long (change to short immediately if any long pass got intercepted - opponent 2 DMCs are huge concerns of counters).
You have better attackers than defenders, so if you want to go for aggressive or need to chase a goal, then can try 3-5v-2.
In-game, move Asrih up from DL to AML, Kourdakis moves from DC to DL, and move Bonokoane up from MC to ST.
(Opponent plays 4 front players, so you must keep 3 defenders + DMC as a minimum, or else it is highly likely to concede more - if opponent remove any of front-4 to go defensive, then you can sub Tenoff off and get Gustaffson on as AMC to become 3-2M-3W-2).
Conditions is quite low there, so hopefully they would have recovered to close to max before the match. Max bonus and max morale should apply as per all title decider.
Best of luck there!
Winning is a form of art. Consistently winning is a show-hand of skills and luck.
